A harvester apparatus, for harvesting crops for essential oil extraction, includes a longitudinal conveyor subsystem and a lateral conveyor subsystem. The longitudinal conveyor subsystem is positionable in crop receiving communication with a harvester header and is configured to convey a crop longitudinally rearward from the harvester header to a transition location. The lateral conveyor subsystem is disposed rearward of the longitudinal conveyor subsystem and in crop receiving communication with the longitudinal conveyor subsystem. The lateral conveyor subsystem is configured to convey the crop laterally from the longitudinal conveyor subsystem to an adjacent crop transport vehicle.
